On-Base Percentage (OBP) measures the most important thing a batter can do at the plate: not make an out. Since a team only gets 27 outs per game, making outs at a high rate isn’t a good thing — that is, if a team wants to win. Players with high on-base percentages avoid making outs and reach base at a high rate, prolonging games and giving their team more opportunities to score.
Every baseball player would love to be able to hit for power, but not every baseball player is a natural like Bryce Harper. There are a lot of things that go into a powerful baseball swing, and no one swing method or form is the right fit for all hitters. However, there are some "Cream and Clear"-free ways that can help all players add power. With the strategy and preparation, you can develop both your mind and body for power hitting as well as improve your form regardless of your preferred stance or swing.

Now that we’ve covered slash line statistics and plate discipline numbers, all that’s left to go over is batted ball data. The most common batted ball stat that is used is batting average on balls in play, or BABIP for short. While a typical batting average tells you how often a player gets a hit in general, this batting average determines how often a player ends up getting a hit when they hit the ball within the field of play. It is calculated by subtracting home runs from totals hits and dividing that by at bats minus strikeouts minus home runs plus sacrifice flies, which translates to the following formula:
These are just a few examples of the many critical factors that come into play regarding your hitting power that go outside the scope of what I can control on the gym floor. Essentially, you can do everything I tell you to do in this article to improve hitting power, but if you don’t have the proper technique to execute and express that power then your first priority is to learn proper batting technique.

HR/FB% – This stands for home run to fly ball rate, which is the percentage of fly balls a player hits that end up as home runs. While this stat doesn’t play much of a role in BABIP due to the fact that home runs are factored out of the BABIP equation, it is definitely a key component of a player’s batted ball profile. HR/FB% is a stat that is largely skill based, but typically doesn’t see much fluctuation from year-to-year, so a player that posts a HR/FB% much lower than their career norm is very likely to bounce back the following season and vice versa.
Just before the pitcher pitches the baseball, you should be standing in a perfect stance so that you can hit the ball right. A good stance includes planting your feet firmly on the ground, slightly wider than your shoulders and your weight should be balanced on the balls of your feet. Such a stance will give you the rapid swinging freedom which you need when swinging the bat at the incoming ball.
Major League Baseball hitters are commonly judged based on their batting average, homeruns, and runs batted in (RBI). Those are statistics familiar to most fans, although they only tell a very small part of the story. Another important statistic is On Base Percentage (OBP). It shows how often a batter reaches base safely, whereas batting average only considers hits.
BAA is very common in evaluating pitchers -- especially when assessing opponent handed-ness splits. A pitcher cannot have an ERA against left-handed hitters because they are interspersed with righties in lineups. So when a pitcher's ability against hitters from each side of the plate is being compared, it is usually done by using either BAA or OPS-against.
